strange symptoms diagnosis please!
 
I have yet another problem.

cold start in the morning is fine. No longer have idle dip as I cleaned the throttle boddy out.

Now sometimes I put my foot down crusinf along and there is hesitation and then whooshhh turrrrbbbbooooo comes on.

Is there some fuel starvation somewhere?

Its not clutch slip nor can it be leads as it is not missing.

what shoudl i check?

probably lean tip-in.

tabs604 12-21-2006 11:19 AM

hmmmmmm..i dont have one of these o2 clamps so maybe!

bripab007 12-21-2006 11:23 AM

Has it just begun to exhibit this problem?

tabs604 12-21-2006 11:46 AM

actually yes. its only recently started doing it.

never had a noticeable problem before.

could it be vacum leak also?

I had a car thru here recently that did a very similar thing. Bad spark plugs and wires.

lol...funny you should say that.

I have been doing some searches and they point to the same cause.

What I really need to do is to diagnose the problem by checking what error codes if any the dignostic box throws.

then replace.

Plugs are the colder long reach NGK's that have been on since january this year so about 11 months.

wiress are magnecor blues been on since decmeber 2004.

think its time for a change.

Stephanie Turner 12-21-2006 05:20 PM

I'd go NGK wires and plugs...
If it is going to pop up with a code, more than likely it will be P0300 - random cylinder misfire. Sometimes, not usually, it will point to a specific cylinder wire. For example P0302 - Plug/wire #2.

I think Autozone and auto parts stores read the OBD codes for free?

Tabs it's a really good idea to change the plugs and lead wires.

Miatas are notorious for going through lead wires quickly.

tabs604 12-22-2006 04:48 PM

UPDATE:

changed the old leads with new ones at my local mazda specialist.

Its still missing.

The checked the coil pack and they said that 2 of the coil pack contacts are corroded and as a result this is causing the missing not the new leads or old leads. As a result they said the coil pack will need replacing !!!:vash: :eek:

I am so pissed now.

Is there a way to clean the contacts on the coil pack?

I found that a brass bore brush of the correct caliber works good while turning in an electric drill. I know you can't have guns, will they report you for buying cleaning gear?:sadwavey:
